application filed January 22, 1823. Serial No. 614,115.

To all whom may concewir Be it known that I, KARL F. NYs'rRoM, a subject of Great Britain, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car Construction, of

which the following is a description, reference being had to the accompanying drawing, which forms a part of my specification. My invention relates more particularlyto railway cars utilized for carrying grain, and the invention has: for its object the provision of means for effecting a grain seal at the juncture of the side and end walls and the floor of the car, whereby leakage of grain will be prevented and the losses heretofore encountered thereby eliminated.

In cars constructed to carry grain, the looring and the sheathing forming the side 11F and end walls are usually formed of coinparatively thick lumber which not only is subjected to shrinkage whereby a separation or opening of the joint between the floor and walls is produced, but the juncture between the floor and walls is also affected or separated by the jaws and racking strains to which the car is subjected.

Another object of my invention is to provide sealing means which will provide a constant grain seal between the walls and the floor and which will maintain constant sealing contact with the end sills and fioor support or underframe of the car and therefore also with the floor proper.

A further object of the invention is to provide sealing means which may be readily applied to cars at present in use, as well as to new cars; and which will also permit the floorboards to be readily removed without the necessity of disturbing the wall sheathin Fhe objects and advantages of my invention will all be more fully comprehended from the detailed description of the accompanying drawing which forms a part of my specification.

Figure 1 is a transverse section through one side of a car provided with my improved grain seal. a v

Figure 2 is a plan view taken on the line 2-2 of Figure 1, at one end of a car, with portions of the floor and the sealing means shown broken away.

Figure 3 is a detail sectional view at the end of a car and taken substantially on the a metallic floor plate or support 6, preferably riveted along one longitudinal side to the upper flange of the channel beam or side sill 5, as shown at 7; while the other longitudinal side of the plate orsupport 6 is preferably suitably bolted to the flooring 8 composed of the tongue and grooved or matched planks as shown in Figures 2 and 3. The ends of the floor planks are therefore firmly secured or clamped in place by the plates or supporting member 6 and held in close juxtaposition to the side wall sheathing 9, as shown in Figure 1; while the floor planks at the ends of the car are supported by the end sills as shown. atlO in Figure 3 where a po 'tion of the end wall 11 is shown. The floor planks 8 are also usually secured and held in place by floorclips 12, bolted to the planks as at 13, and arranged in lapping relation with the upper flange of the center sill member or beam 14., j

The construction thus far described is a well known type employed for grain cars and, as is apparent, permits the flooring to be readily renewed or put into place.

VVith this construction, however, the racking strains to which the car is subjected, as well as shrinkage, causes aseparation of the butt fit or junctureand therefore produces crevices through which the lading of small grain, especially such as flarcseed, will leak and therefore entail considerable loss.

In order to overcome this difliculty and prevent the excessive losses that have been encountered, I provide the sides and ends of the car with a sheet metal plate or pliable fiashing 15, preferably of galvanized iron to withstand the action of moisture; the flashing being adapted to extend from end to end along both side walls of the car, that is to say intermediate of the car-ends and the door-posts and also from side to side at both ends of the car. f

V The flashing strips or plates 15. are bent longitudinally into angular formation so as to have one portion disposed substantially parallel and flush with the side sheathing 9 or the end wall sheathing 11; while the other portion is disposed about the edge of the floor planks and beneath the planks, where it is arranged intermediate of the flooring and the floor support 6 at the sides of the car and intermediate of the flooring and the end sills 10 at the ends of the car. The lower, horizontally disposed longitudinal edges or legs of the flashings or sealing strips 15 are firmly clamped or held in place, at the sides of the car, by the sup porting plates or members 5 as well as the upper flanges of the side sills (see Figure 1) and at the ends of the car by the end sills 10, as shown in Figure 3.

The upper longitudinal edges of the sealing plates or fiashings 15 are preferably angularly disposed and driven into or arranged in a small groove in the side Wall sheathing 9 at the sides of the car and into the sheathing 11 at the ends of the car as shown at 16 in Figures 1 and 3.

The small crevice between the ends of the planks and the upwardly disposed legs of the flashings or sealing strips is preteraliily calked with a suitable material such as oakum or the like, thereby preventing any small grain lodging between the flashing and the planks and also preventing moisture, while the car is being cleaned, from passing or seeping beneath the floor planklily improved sealing strips or tlashings are preferably made of galvanized sheet iron to withstand the action of moisture; and the flashing at suitable intervals is also preferably securely fastened to the sheathing-by suitable nails as shown at 17 in Figure l.

In the construction of car disclosed in the drawing, where. the floor supports or fastening elements 6 are employed and riveted to the side sills, the lower inner edge of the side sheathing and the adjacent lower ends of the floor planking are preferably beveled as shown at 18 in Figure 1, and the sealing members or strips 15 are therefore given the inclination between the vertical and longitudinal portions of the flashing as shown at 19 to provide a flush. fit about the lower edges of the floor planks. It is apparent from the construction shown that the car may be constructed with the floor planks terminating at the inner face or surface of the wall sheathing instead of kerfing the wall sheathing to receive the floor planks as is the case in some grain cars as heretofore constructed. Constructing and securing the floor planks as shown enables the ready removal of the planks, when occasion requires without disturbing the wall sheathing; this type of construction for grain cars'being possible because of my improved sealing means whereby grain-tight joints at the intersection of the floor and side and end walls is provided; which will not be disturbed or affected by shrinkage or racking strains; as the sealin strip is preferably of flexible or pliable metal not fixedly or rigidly secured to the flooring, but having a considerable lapping relation with the flooring; while at the same time sealing means of comparative simple construction, readily applicable to either new or used cars, is provided.

The form of my improved sealing means and the method of application I believe to be the simplest embodiment and application of the invention which has been described in terms employed merely as terms of description and not as terms of limitation, as structural modifications may be made without, however, departing from the spirit of my invention; my improved sealing means at the same time providing a gutter or moisture conveying medium, whereby moisture from the car interior will be diverted beyond and away from the frame members of the car underframe.

lVhat I claim is 1, In a car construction, the combination of sheathing which rests on the car-sills, floor boards which. terminate adjacent to the inner sides of the sheathing and above the bottom edges of the sheathing, in unconnected relation therewith and means for supporting the floor boards, with pliable means interposed between the inner faces of the sheathing and the edges of the floorboards, adaptcd to be secured against the sheathing and provide a lapping joint with the under surfaces of the floor-boards.

2.

3. In a car construction, the combination of the wall sheathing. flooring and means for supporting the floor, with angularly formed thin metallic sheets arranged along the sides and ends of the flooring, one portion of each sheet being disposed vertically in the same plane as the floor planks and secured against the wall sheathing, while the other portion is arranged parallel with the under surface and in unattached lapping relation with the flooring, said last portion being held in place by said supporting means.
